7 x^{2} - 13 = 50

x = 3, x = - 3

Solution steps

7 x^{2} - 13 = 50

Move

13

to the right side

7 x^{2} = 63

Divide both sides by

7

x^{2} = 9

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

x^{2} + 5 x - 2

x, x^{2} + 2 q x + 2 q + 8 = 0

x^{2} - 2 x + 36 = 0

4 x^{2} = 4 x - 1

(2 x + 3) (x - 4) + (2 x + 3) (x - 6) = 0
